Hi Hamad, welcome to study pool. there are lots of tutor ready to help you. if you need anyone to help you on an online assignment please do this. login and go to the question you want anyone to assist you with. Take a screen shot and post it here as a question. You will have lots of bids, you can choose the one you like. Now if you do not knew how to take a screen shot, you press the PRT sc Key on your keyboard. If you are using a laptop, you may have to combine it with the Fn key. Alternatively you can use a snipping tool to get the image. If they are many questions you may chose to screen shit all of them in to one PDF file and upload them on studypool to have tutors look at them. You will surely be helped. in case you need further clarification on the process let me know.
